SPECIFICATION forming part of Letters Patent No. 635,122, dated October 17, 1899;

Application filed March 28, 1899.

on iron girders, where such may be temporarily required.

In order to render the present specification more easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a side elevation of the hanger attached or hung onto a girder; Fig.2, a similar elevation of the same hanger applied to a girder of smaller cross-section Fig. 3, a front elevation of the hanger; Fig. 4, a section showing the application of a pair of hangers to support planking on two girders; Fig.5, a section on line N N of Fig. 4:; Fig. 6, a plan showing the application of two hangers to support an arched planking, and Fig. 7 a sectional elevation of the device illustrated by Fig. 6.

The hanger consists of the shank a, having a hook I), said hook being bent around at an obtuse angle to the said shank, in order to prevent it from lying on the flange of the girder with its whole surface, which would cause breakage if the hanger were very heavily loaded and the form of the girder were such that it did not lie evenly on the whole surface. From the lower part of the shank a a fulcrum-arm 75 extends, being arranged at an acute angle to the said shank and adapted to press with its upper end against the lower Serial No. 710,809. (No model.)

side of the girder. At'the opposite side of the shank to that at which the arm 75 is pro vided are arranged a pair of lugs g g, in which a carrier-bar p is mounted to turn, said bar serving to support the planking. Y

The application of the device will be evident from Figs. 4 to '7. In Figs. 4 and 5 two hangers are employed, one at either side of the beam 70, which may be supported on wedges inserted between the carrier-bar and the said beam, and thus the planking supported be tween the girders h h. WVhen the planking is to be removed, the carrier-bars may be simply turned on their hinges and the whole planking allowed to fall down. In Figs. 6 and 7 arched plankingisillustrated,also supported by means of two hangers and a templet d.

The advantage of the present hanger is that the same maybe conveniently applied to girders of any cross-section.

I claim as my invention- A hanger for supporting planking on girders of any cross-section, which consists of a shank having an upper hook bent around at an obtuse angle to the said shank, afulcrumarm extending from the lower part of the shank at an acute angle to the same upwardly and adapted to engage the under surface of the girder and a carrier-arm pivotally connected to the opposite side of the said shank at the lower part of the same to turn in a horizontal plane in the manner and for the purpose substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

AUGUST BREMER.
